Is it worth hauling a steel tank?

I Love LP Steel Tanks because they are full at 2400psi, and you can overfill them which gives you more (for ex: a LP 121 cu ft overfilled to 2650, has 131 cu ft of Air), ..........

I believe LP tanks are marketed at their "plus fill" rating. Your 121 is a 121 cf at 2640 psi, 109 cf at 2400psi.

You cave dive with LPs, but don't understand how they're actually rated for capacity?

I Love LP Steel Tanks because they are full at 2400psi, and you can overfill them which gives you more (for ex: a LP 121 cu ft overfilled to 2650, has 131 cu ft of Air), for the most part i dive with Double LP 108's in Caves, and either Double LP 121's in OW or Double AL 80's depending on the dive site/depth etc... either way Steel tanks are best because you can take lead off your belt, they are not positivley Bouyant at the end of a dive, and they can be overfilled squeezing more air into a smaller tank as supposed to carrying a larger more bulkier tank....

I used to haul my HP120s and my 36# weight belt wherever I went. Now I have an neutral buoyancy Al tank that I do the same with. I dive DIN and prefer to have my full kit with me when I dive. Of course if I have to fly to get there, I rent.

I've never been a fan of LP tanks (for the type of diving I do, your mileage may vary) and didn't even know they made a 121 that could have a plus rating! Learn something new every day.
